Well the reason I can't work in 800x600 isnt purly because of websites, I tend to have lots of windows open and specialy msn ones, with msn 1window seems to take nearly the entire screen, and I like to be able to multitask ..
But yeah, if a website is supposed to be optimised for all users it should be lowest res, but most websites nowadays feel that the 'user experience' would be greater enhanced by a larger size I guess.... because it does feel easier having to scroll less (since much more info is on a webpage nowadays)
